Embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained, shall fall within the protection scope of the present invention.

Referring to Fig. 1, the utility model embodiment provides a kind of micro motor shell for facilitating end cap to install, this facilitates end The micro motor shell of lid installation includes outer cover body 100.

As shown in fig.2, the 100 generally cylindrical structure of outer cover body, along its axial direction, its both ends is respectively openend 110 and blind end 120.It should be noted that the blind end 120 is not completely enclosed, being internally formed for outer cover body 100 is used for The accommodating chamber of motor is installed, and the openend 110 and blind end 120 are connected with accommodating chamber.

Refering to shown in Fig. 3 and Fig. 4, in the present embodiment, for the ease of the installation of end cap, it is provided with least in openend 110 Four notches 140.

With reference to shown in Fig. 1 and Fig. 4, wherein, the quantity of notch 140 is even number, is using the quantity of notch 140 as four , then two of which notch 140 forms one group and is disposed adjacent, two other notch 140 forms one group and is disposed adjacent, and two Group notch 140 is symmetrical arranged, and specifically, which includes Part I and Part II, and Part I is relatively distant from envelope Closed end 120, the relatively close blind end 120 of Part II, and Part I is rectangular, Part II semicircular in shape.The notch 140 Be mainly used for end cap installation when (end cap is installed on the openend 110 of outer cover body 100), will be bent in the riveting position on end cap to In notch 140, so as to complete the assembling to end cap.
